I was going to put it in rifles, but it applies to shotguns as well, so I put it here.

They say it has approx. 80 feet of paracord that you can unravel when needed in an emergency. I think it would make a great carry sling for back country hunting trips where having some survival gear may come in handy.

Kind of neat I think.
